  • Page 17: Preparations

    PREPARATIONS ASSEMBLY/INSTALLATION OF NEAR-POINT ROD AND NEAR-POINT CARD Insert the near-point card into the end of the near-point rod. The near-point card is designed to slide on the near-point rod. Insert the near-point rod into its holder and tighten the clamp screw securely. When the near- point rod is not in use, set it upright.

  • Page 18: Level Adjustment

    LEVEL ADJUSTMENT Before using the instrument, check if it is horizontal, using the level. If there are not bubbles between two red lines, turn the leveling knob to make the instrument horizontal. Level Leveling knob FIXING THE TILTED HEAD By tilting the head in the near-point test, the instrument can be set in the proper position for the real near-point test.
  • Page 19 Do not rotate the instrument while the tilt fixing lever is loosened. The NOTICE tilt fixing lever may hit the mounting arm to damage the instrument. Do not put your hand between the arm and the instrument. Your hand CAUTION may be pinched to cause injury.

  • Page 20: Near-Point Card

    NEAR-POINT CARD When the patient wears the multi-focal lenses, measure the eyeglass refractive power at near distance. For installing the near-point rod and near-point card, refer to "ASSEMBLY/INSTAL- LATION OF NEAR-POINT ROD AND NEAR-POINT CARD". Incline the near-point rod until it stops. If the near-point rod is almost horizontal, the position is the measuring position.

  • Page 21: Operating The Instrument

    OPERATING THE INSTRUMENT Press the main switch on the CV power supply. The instrument is reset. Perform the objective measurement by an auto refractometer and set the measurement data in the instrument. In this case, optometry by fogging method and others can be omit- ted.

  • Page 26: Optometry

    Mr. A, an adult aged 25 wearing eyeglasses comes to the store. He complains about his insuf- ficient visual acuity. After we have checked the refractive power of his glasses with the TOPCON lens meter, the following results are obtained.

  • Page 27: Optometry By Fogging Method

    OPTOMETRY BY FOGGING METHOD For the right eye, add +3.00D to the expected spherical power. Since the current eyeglass refractive power is -1.00D, the right spherical power is +2.00D. His eyesight fails to almost 0.1. (Adding +3.00D to the spherical power enables to drop his visual acuity to almost 0.1.

  • Page 28: Accurate Measurement Of The Astigmatic Axis And Astigmatic Power (When Using The Cross Cylinder)

    ACCURATE MEASUREMENT OF THE ASTIGMATIC AXIS AND ASTIGMATIC POWER (WHEN USING THE CROSS CYLINDER) Set the dot chart as the target. The cross cylinder status "1" is set for the right eye (dial mode A) and the accurate measurement mode of the astigmatic axis is accessed. Press "1"...

  • Page 29: Accurate Measurement Of The Spherical Power (Red-Green Test)

    ACCURATE MEASUREMENT OF THE SPHERICAL POWER (RED-GREEN TEST) Next, make an accurate measurement of spherical power. Set the red-green chart, and the spherical movable mode is automatically set. Ask the patient which side is seen better, red or green. He answers the green side is seen a little better. Since this means that myopia is a little strong (or hyperopia is a little weak), increase the spherical power by +0.25D.

  • Page 30: Binocular Balance Test

    BINOCULAR BALANCE TEST Measurement by using the polarizing filter Set the binocular balance target. Apply the polarizing filters to both eyes and access the binocular spherical movable mode. Mr. A sees the upper line with the right eye and the lower line with the left eye. If he can read up to the same place on both lines, the binocular balance is obtained.

  • Page 31: Measuring Phoria (Far-Point)

    MEASURING PHORIA (FAR-POINT) Measurement by using the polarizing filter Only in CV-5000 Set the cross target. Apply the polarizing filters to both eyes and access the binocular prism movable mode-horizontal (H). If no phoria is found in the patient, four lines are seen as a cross. If the patient has phoria, the four lines are seen differently.
  • Page 32 Measurement by using Maddox rod and rotary prism Only in CV-5000 Measure horizontal phoria first. Access the binocular mode. Apply the red horizontal Maddox rod to the right eye with the right auxiliary lens selector switch, and make the left eye uncovered. Turn on the fixation target (small dot of light) at the target position.

  • Page 33: Summing Up Measurement Results

    SUMMING UP MEASUREMENT RESULTS The visual acuity test of Mr. A is finished. If much phoria is found in phoria measurement, the visual acuity needs to be corrected with eyeglasses. For the visual acuity of Mr. A, correction is not necessary. Therefore, his eyeglasses will be prepared according to the following data: : 64mm Right eye : S-1.25D...
